The unofficial blog phenomenon intrigues me. This is a great post, but what happens when an unofficial blog (or Twitter account) posts something controversial? Breaks the law? What recourse does the company (or govt agency) have? I'm not really denouncing the unofficial blogs, but I can see it making PR people uncomfortable, and understandably so. On a personal level, it seems like an easy way to use the name of your employer (btw, how do we know they're really employees of X) as a springboard for popularity, without the huge responsibility that comes along with officially representing the organization.
